2. Use the adjustment nut on the PTO clutch actu-
ator assembly (refer to PTO Clutch Linkage
Adjustment photo) to set the tension applied
by the PTO clutch lever. The adjustment nut is
initially set to achieve an approximate measure-
ment of 2-3/4" between the jam nut and the
knuckle joint. As the belt and pulleys wear, it will
be necessary to tighten the adjustment nut in
order to prevent belt slippage--this adjustment
is the same in the Engaged and Disengaged
positions.
Do not overtighten the adjustment nut. This may
cause damage to the clutch linkage and the PTO
belt.
PTO Clutch Linkage Adjustment
Transmission Control
IMPORTANT: The proper adjustment of the trans-
mission control stops is essential for efficient oper-
ation and life of the transmission. These stops are
properly adjusted at the factory and should only re-
quire readjustment if the transmission or related
control linkage is removed or changed.
NOTE: It would not be unusual for a new machine,
after initial 5 or 10 hours of operation, to begin to not
travel straight (this is due to the break-in of the trans-
missions). In this case, proceed to Tracking Adjust-
ment - Step 4.
IMPORTANT: The following adjustment proce-
dures are sequential. Check and adjust each func-
tion in the order given.

located in the steering pivot rod (as shown).
2. Turn the ignition key to the ON position and tog-
gle the FSC switch to the Neutral position (fully
retracted).
3. Tighten the adjustment bolt until it contacts the
chassis and turn an additional 1/2 turn. Tighten
jam nut.
